Landscape between the two sides of the horizon

Description: Follow this astounding panoramic image across the horizon, where you can see the dark night sky above the Pic du Midi observatory. In order to complete the sky journey above the sea of clouds, 19 photos taken on the night of October 31st, will be combined using the Mercator projection method to keep the horizon on both sides straight. At the top of the image, you will look east up and down the dome of the 1 meter telescope at the Observatory. Then along the face of the Milky Way, which looks like it sticks out of the dome, it can slant to the horizon on the other side. In the sky on the right side of the disk, there is a bright diffuse ecliptic light distributed around the ecliptic plane of the solar system. The sacred masses, the galaxy and the faint nebula in the Milky Way and the Milky Way pass through the zenith and then stretch toward the West, and finally hide behind multiple domes and towering communications interrupted antennas near the lower west horizon.
